Just finished flashing... I like how the HTC splash screen says Test Only - Not For Sale
(Easy enough to replace, I know... but I wasn't being sarcastic, I actually like it.)
I let the customizations run. During the process it connected to the Data network, went to landscape and back to portrait without me hitting anything. Fun.
I did a speed test.... before the update (Using Alltel radio and either gf's v7 or omj's rom, don't remember which but they're both good) I was getting around 1200 down and 100 up, and it was landing me in Chicago as the closest point, now it has me near Atlanta getting 1896 down and 207 up.
Going to download google maps and give the GPS a try (although I'm in an office building, so who knows).
